Anne-Sophie Mutter (born 29 June 1963) is a German violinist. Born and raised in Rheinfelden, Baden-Württemberg, Mutter started playing the violin at age five and continued studies in Germany and Switzerland. She was supported early in her career by Herbert von Karajan and made her orchestral debut with the Berlin Philharmonic in 1977. Since Mutter gained prominence in the 1970s and 1980s, she has recorded over 50 albums and performed as a soloist with leading orchestras worldwide and as a recitalist. Her primary instrument is the Lord Dunn–Raven Stradivarius violin.

Mutter's repertoire includes traditional classical violin works from the Baroque period to the 20th century, but she also is known for performing, recording, and commissioning new works by present-day composers. As an advocate of contemporary music, she has had several works composed especially for her, by Thomas Adès, Unsuk Chin, Sebastian Currier, Henri Dutilleux, Sofia Gubaidulina, Witold Lutosławski, Norbert Moret, Krzysztof Penderecki, André Previn, Wolfgang Rihm, Jörg Widmann, and John Williams.
